HDF格式,为影像常用的格式。里面有许多的子文件,在用AE打开影像的时候,按照AE常规的方式打开影像的方式是行不通的。先把HDF中需要的文件,提出来,再按常规的打开影像的方式打开。下面代码为提出HFD文件中的子集:
public IRasterDataset HDFSubdataset(IRasterDataset rasterDataset, int subsetID)
{
//Some raster formats can contain multiple subdatasets inside a single file, for example the HDF format.
//This sample code shows how one can retrieve the HDF subdatasets using the IRasterDatasetJukebox interface.
//rasterDataset: represents a raster dataset from a HDF4 file
IRasterDatasetJukebox hdfDataset= (IRasterDatasetJukebox)rasterDataset;
IRasterDataset subDatasset;
int datasetCount = hdfDataset.SubdatasetCount;
if (subsetID < datasetCount)
{
hdfDataset.Subdataset = subsetID;
subDatasset = (IRasterDataset)hdfDataset;
return subDatasset;
}
else { return rasterDataset; }
}
然后就打开subDataset就可以了。。
